Sowing machine



SOWING MACHINE Filed Feb. 25, 1954 patented May 12, 1935 H'UNITED STATES PATENT OFFICE Ernst Johan Oscar Magne, Visby, Sweden Application February 23, 1934, Serial No. 712,649 In Sweden March 13, 1933 2 Claims.

The present invention relates to a sowing machine adapted to be drawn on wheels and intended for instance for potatoes or seeds, and in which the potatoes and the seeds respectively are automatically supplied from a receptacle, when the machine is being drawn.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a diagrammatical vertical section of a sowing machine for potatoes in accordance with the invention.

Figure 2 is an enlarged detail view of a supplying drum adapted for small potatoes and Figure 3 is a detail View of a corresponding supplying drum for large potatoes.

Fig. 4 is a longitudinal sectional view of the drum.

Referring to the drawing numeral I indicates a frame provided with a beam 2, and supported by two wheels 3 on an axle 4. The frame I supports a tapering hopper 5, the bottom of which is provided with an outlet opening 6 directed obliquely forward. A rotatable shaft 9 is mounted in the rearwardly slanting front wall 1 of the receptacle 5 and in a member 8, which is secured to the shaft 2, said shaft 9 slanting at an angle of about 45 relatively to the horizontal plane. A drum I open at both ends is secured to the said shaft 9 and at the end facing the front wall I provided with a bowl-shaped extension II. Along its circumference the inside of the bowlshaped extension II is provided with radial partition walls I2 which extend towards the center to provide separate cells I 3 each cell being about the size adapted to receive a potato. These cells I3 are open at their inner ends. The partition walls I2 are further each divided at substantially the center to form a gap, the several gaps beingarranged in the form of a circle.

A finger or projection I4 is attached at its inner end or front wall of the receptacle 5. This finger or projection I4 extends into the gaps between the portions of the broken walls I2 and which slants relatively to the bottom plane of the bowl-shaped portion, so that it is able to extend below the potatoes in the cells and lift them. Around the lower portion I of the drum In there is a driving belt I8, which also is laid around a belt pulley l8 having a conical toothed wheel I! and being freely mounted on a shaft I9 in such a manner that the conical toothed wheel I! meshes with a conical toothed wheel provided on the axle l and rotating with the wheels of the machine, the shaft I9 being supported by the axle 4 and the member 8.

If desired a pipe 24 may be attached in any convenient manner to the frame I to facilitate the guidance of the potatoes as they leave the drum II] to a desired point rearwardly of the ploughshare 2|.

A cover 23 may also be arranged over the top of the drum If! to prevent the potatoes from shaking out. This cover 23 is attached to the frame I in any manner desired and does not partake in the rotation of the bowl.

In front of the lower end I5 of the drum I0 and at the ground the machine preferably is provided with a ploughshare 2| to furrow the ground for the potatoes and behind the drum II], also at the ground, the machine is provided with one or two shovels 22 for subsequently filling up the furrow.

The device operates as follows: Potatoes placed in the receptacle 5 leave successively through the opening 6 and fall into those cells I3 of the bowlshaped portion II of the drum I0, which are furthest down at that time. When the machine is being drawn the wheels 3 rotate the drum If] by means of the conical toothed wheels I! and 20 and the driving belt I6, so that the cells I3 filled with potatoes will move to the highest portion of the bowl-shaped portion II, where the finger I4 enters between the two portions of the walls I2 and forces out the potato in question, so that it, will fall down through the lower open end of the drum I0 into the furrow in the ground below made by the ploughshare 2|.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A sowing-machine for seeds and potatoes having a receptacle open at its lower end, a drum provided in front of the said receptacle, said drum being open at both ends and adapted to rotate about a shaft slanting at an angle of about relatively to the horizontal plane, the upper portion of the said drum being provided with a bowl-shaped extension with radial walls extending some way toward the center and dividing the circumference of the bowl-shaped portion into sections or cells, the drum, by way of a driving belt, being driven by wheels supporting the sowing-machine, characterized by the fact that the radial walls are broken, and that a finger is secured to the front wall of the receptacle, said finger extending into the interspace between the two portions of the broken walls and slanting relatively to the bottom plane of the bowl-shaped portion.

2. A sowing-machine for seeds and potatoes having a receptacle open at its lower end, a drum provided in front of the said receptacle, said drum being open at both ends and adapted to rotate about a shaft slanting at an angle of about 45 relatively to the horizontal plane, the upper portion of the said drum being provided with a bowl-shaped extension with radial walls extending some Way toward the center and dividing the circumference of the bowl-shaped portion into sections or cells, the drum, by way of a, driving belt, being driven by wheels supporting the sow-.- ing-machine, characterized by the fact that the radial walls are broken, and that a finger ls secured to the front Wall of the receptacle, said finger extending into the interspace between the two portions of the broken walls and slanting relatively to the bottom plane of the bowl-shaped portion and further characterized by the fact that part of the bowl-shaped portion is covered by a covering member so as to prevent the seeds or potatoes from being shaken out of the cells.
